framework le which includes horizontally disposed beams Lili and a plurality of vertically disposed uprights L35 have their upper ends secured to the beams is and their lower ends secured to the vehicle 39.

Projecting upwardly from the beams d!! and secured thereto, as by welding, is a plurality oi spaced parallel vertically disposed uprights 455 which are secured to the lower portion of a stationary frame 4l. The frame 4i' is preferably fabricated of channel shaped beams as best seen in Figures 2 and ll. gasoline driven motor 48 is arranged adjacent the frame di, and the motor it serves to opcrate theharvesting machine as later described. The frame i? includes a pair of spaced parallel sections 49 and Q9 which have extending therebetween and secured thereto, a plate 5c which prevents the brush heads H from falling onto the vehicle 3D.

Arranged above the front part of the vehicle 3E! is a movable frame 5| which is mounted for The movable frame 5i includesI a pair of spaced parallel vertically disposed sections 52 and 52 which are preferably fabricated of angle iron. Each of the sections 52- and 52 includes a lower beam 53, a vertically disposed beam 5e, and an upper beam i5 which extendsbetween the beams 53 and 54 and is secured thereto. Extending be- 'tween the sections 52 and 52 and rotatably supported by the latter is a horizontally disposed shaft 55 and the upper ends of the piston rods 42 are rotatabh7 connected to the shaft 5t.

Thus, uponv actuation of the hydraulic lifts ed land di, the front of the frame 5| can be raised -or lowered as desired.

A hinged connection is provided between the meeting ends of the moveable frame 5l and the stationary frame 4l and this hinge connection` is shown in. detail in Figure 14. The hinge con nection includes a first short shaft 5l which eX- tends through the upper rear portion of the section 52 of the frame 5|, and the shaft 5l also .p roiects through an arm 8- of an L-shaped tie -rod 59.

The other arm 59 of the tie rod 55 is secured to the section e8 of the stationary The shaft 5l is keyed to the arm 53 mounted on the shaft .5l and an endless chain .E2 is trained over the sprocket 5| for a purpose slr'. the frame 5|. A tie rod 64 has a transverse arm -SE-keyed to the shaft S3 as at 5E, and one end 6l' of the tie rod 54 is secured to the section A sprocket 53 is loosely7 mounted on the shaft 53 and a chain 69 is trained over the sprocket 33. Also Yarranged on the shaft 53 is a bearing sleeve ifi .which rotatably supports a transmission wheel 1|. The transmission wheel H is shaped to delfine a pulley l2 and also a gear f3 is formed on the wheel li. The gear i3 is arranged in meshing engagement with a bevel gear 'is which is mounted on an end of a lshaft T5, the shaft l5 being rotatably supported by a bearing bracket 16. A bevel gear 'il' is also arranged in meshing .engagement with the bevel gear 13, :and the bevel gear il is mounted on an end of a shaft 18, the shaft l?. being rotatably supported by a bearing arm which is part of the tie rod Thus, upon actuation of the hydraulic lifts d and lll, the frame 5| will be pivoted` about A power source, such as a an axis extending through the shaft 2.53.

A conveyor means is provided for carrying the severed tops or brush heads H through the machine, and. this conveyor means includes the pair of endless chains t2 and 5S which are trained around the frames di and 5l, as best seen in Figures 2 and 3. The conveyor is designated generally by the numeral iii and includes a plurality of support members 8| arranged in spaced parallel relation with respect to each other. The ends of the support members'ill are secured, as by welding, tc the chains $2 and (is and carried by each of the support members @l is a plurality of spaced parallel wire fingers S2 which engage the. tops or brush heads l-l, after they have been Seyer-ed from the stv fr plate sections 52 and 52' so that the possibility of any material falling onto the vehicle or the operator thereof is precluded.

Referring .to Figure 7, there is shown a diagrammatic viewof the driving mechanism for the broom corn harvesting machine. Thus, the gasoline engine @8 drives a shaft 83 and mounted on the shaft 83 is a pulley 84, there being a pulley 35 spaced from the pulley 64. A belt 86 is trained over the pulleys 84 and 85. The pulley 351s mounted on a drive shaft 81, the drive shaft Sl being rotatably supported by bearingbrackets 83. Mounted on the other end of the drive shaft Alil is a pulley 89 and a belt 90 is trained over .the pulley 39 and over the pulley 'l2 so that rotation of the drive shaft Si causes the pulley 'i2 to rotate. Since the gear 'E3 is formed integral with the pulley l2, rotation of the pulley 'I2 will cause the shaft 'l5 to rotate and also the shaft .i8 will berotated. .f

The shaft .i5 extendsralong one side of the frame 5| and suitable bearing brackets 9| coact with the bearing 'i5 to rotatably support the shaft on the frame 5l. A, bevel gear52 ismounted on the front end of theY shaft 'I5 and the bevel gearSZ is arranged in meshing engagement with a bevel'gear 93 that is arranged on the adjacent end of the shaftlt. Thus, as the shaft l5 roe tates, the shaft 5S will likewise4 be rotated, A pair of sprockets 2l are mounted o n the shaft 5G and the chains t2 and 59 are trained over the spockets 21. so that the endless chains @Zand 5S will'be caused to travel whereby the support members 3| will moveA thus conveying the severed brush heads H through the machine. The chains |52 and 5S are Valso trained over suitable sprockets 96 and. 95 which are rotatably supported in the stationary frame 41.

A vcutting mechanism is vprovided forsevering the tops or brush heads H from thev stalks S, Figures 2, 3, 5 and 6, as the vehicle `3El movesf along the'rows of growing stalks.` This cutting mecha'- nism is arranged at the front end of the machine and embodiesa pair of stationary ledger plates 96 and S6 which are each provided with a sharp edge 9i. Coacting with the ledger plates BSand 96' to shear the heads H from the stalks is a pair of reciprocating cutting knives or blades 98' and 98"; The rear ends of theV knives 88 and 98'.. are

y"secured to a body member 9S and the bodymemlthe ear ||l| to the pitman |92.

The other end of the pitman m2 is pivotal-1y assess;

'a bevel gear |54 which is mounted on the lower end of a short shaft |55 and'secured to the upper end of the shaft |55 is a bevel gear |56. The gear |56 is arranged in meshingengagement with a gear |51, and the gear |51 is secured to a shaft |58, the saw |3| being mounted for longitudinal movement on the shaft |58. Thus, the shaft 18 rotates, the shaft |35 is also rotated, and this in turn drives the shaft |58 to thereby rotate the saw |3| and the brush heads H can be trimmed to any desired length, depending upon the relative position of the saw I3| with respect 'to'the table |24.

A means is provided for causing the brush heads H to lie flat as they are conveyed along 'the table, to insure proper trimming by the saw f|3|.` Thus, a pair of spring pressed feet |59 and |59 extend longitudinally along the table '|24 Vandthe presser feet |59 and |59' are spaced just above the table. The presser feet |59 and |59 are secured to the lower end of a plurality of bolts |69 and the upper endsV oi the bolts |60 project through a horizontally disposed cross bar YI6|, the cross bar IBI being secured to the frame 41 by suitable bracing. A coil spring |62 is circumposed on each of the bolts |60 whereby a slight pressure is exerted against the brush heads H. One end of each oi the presser feet` |59 and |59' 'is' curved or shaped arcuately as at |63 to facilitate the movement of the brush heads to a position therebelow, after the heads have left the conveyer 88. The pair of presser feet |59 and`I59 are arranged in spaced parallel'relation Vabove the chain |42 and a similar pair of spring pressed presser feet |64 and |64 are arranged above the chain Sell.

A manually operable adjustingY means is provided for shifting the'pla-tforin |5941 whereby the lsaw iti can be moved in order to trim the brush 'heads H to any desired length. Further since 'the saw |3i can be moved, there will be an assur- "ance that the machine will operate when long or short'stalks of grown corn are being processed through the machine.. This adjusting means is Vconnected to the horizontally disposed shaft |58 l which is rotatably supported by a bearing block 69 that is secured to the undersurface ofthe table |28. The rear portion of the. shaft |58 which is rotatably supported by the bearing block ':|66,.is,pr.ovided with a key `way iland thehub |61 offthe` saw 63| is arranged in engagement uwith thekey way it' so that as the shaft |53 ro- ;.tates'the saw |3| will also be rotated. A bracket |68 has a pin |59 pivotally connecting' an arm :|12 thereto, and the arm |12 carries a manually operable keeper or pawl, |19 which is adapted to ,be moved into engagement with one or" the teeth ,i 1| in a sector plate |18 for maintaining the saw |3| or platform |39 immobile in their adjusted iposition, Figures i8 and I9. A link |14 is secured tothe arm 1i and the link |14 is provided with a `slot 2,15 which receives therein a pin |16 that projects from a collar 511, the collar |11 being rotatably mounted on the shaft |58.\ The collar |11 is interposed between a iiange |18 which is lsecured to the shaft |58 and a second flange |19 ,which is arranged on an end of a sleeve |88, the sleeve 599 being mounted on the shaft |58. The Vhub |61 is interposed between a pair of ears I8| :and H52 which are secured to the undersuriace of .the platform |88. Thus, upon pivotal movement of the arm |12, the hub |61 which carries the saw'lii will be moved longitudinally along the shaftl |58 and also the platform. |30a will be giovedi i -i 'l V 1 8 After the brush heads H have been trimmed to their proper length by the saw |3I,the brush heads are conveyed pasta plurality of revolving wire brushes |83. The brushes |83 are mounted o'a shaft |84 and mounted on one' end of the shaft |84 is a bevel gear |85 meshing with a bevel gear |86. The gear |86 is mounted on a shaft |81 and the shaft |81 has secured thereto a pair oisprockets |88 and |88' which are arranged in meshing engagement with the chains |42 and I whereby the brushes |83 are revolved as the shaft 16 rotates. The wire brush |83 serve to strip seeds and leaves from the brush heads after the heads have' been trimmed.

"After the brush heads H have been trimmed and stripped of their leaves and seeds, they are conveyed bythe'conveyer |32 to a trough or carrier' |89, the carrier |89 having a substantially V-shape and being supported on braces |90 which project from the frame work 43. l

The operation of my device is as follows:

` The vehicle 30 is driven through the eld of growing broom corn stalks S with the operator sitting in theposition shown in Figures 2 and 3. The motor 48 drives the shaft 83 and the shaft 83, through the beltBS, causes the shaft 81 to rotate. This results in the shaft 15 being rotated since the belt 9E)` connects the pulley 89 to the pulley 12. Rotation or the shaft 15 causes the knives 98 and 9X8? to reciprocate and the knives coact with the ledger plates 96 and 96 to shear therebetween the brush heads or tops H from the corn stalks S. The rotary reel |99 is driven by a beltv |"I4 which is .trained over a pulley I5 that is mounted on the Ishaft 56. The rotating reel |99 forces the stalks to be moved through `the space between thearms |98 and |88(` and into engagement with the cutting knives and ledger plates. `After the heads H have been severed by the cutting mechanism, the heads H are deposited on the conveyer 8 9 and the fingers 82 gripthe brush heads and start to move the brush heads upwardly and rearwardly through the machine. At this time, vthe brush heads arelying on the conveyer'in an irregular manner but as the brush heads pass blo,w the plate member |2| pressure is applied to thev brush heads so that thevupper ends of the brush heads A become `aligned on the conveyer. Ihe brush-heads are conveyed further to the rear and upwardly by the conveyer and lnally as shown in Figure 3, as each bundle of brush heads l-I passes beyondhthe frame 41, the kicker'25 moves to disengage the bundle of heads from the lingers 82 -and the brush heads are deposited on thetable E24. l fjf'Next, the conveyer I grips the brush heads H and moves the brush heads into engagement with the rotating saw |3I, whereupon the lower or butt ends of the brush heads H are trimmed by the saw. The trimmed ends are discarded and the'v remaining portion 4of the brush heads are carried by the lingers |41 and |43 over the rev'olving wire brushes |83, and the wire brushes |83 serve to remove or strip any leaves or seeds vfrom the brush heads H. After the leaves and seeds have been stripped from the brush heads,

:the'ffingers |41 and |43 of the conveyer |32 carry the brush heads over and drop the brush heads into the carrier |89 and the brush heads may be emptied from the'carrier or trough |89 in any desired manner. i 1 PY"lhe machine is so constructed that the front vportion thereof can be raised or lowered when it' is desired to sever the heads from stalks of various I lengthsl Thus, to raiseor lower the front atea-,esa ff andi 4 are` actuated whereupon the rods 42" are moved verticallyil "Thus,- in Figure 2, the front-of 'Y the machine is `shown in ai lowered position: when short" stalks are being out, While Figure 6", the* front off the machinerie shown raised position for* sever-ing brush heads from l tal-1f stalks. This l movement ofi thef apparatus from* the` position ofi Figure 2 tothe positionof-Figurel 6 is] accom?` plished by actuating the lifts 40 and-4| vvlieree upon the rods 42 riiclive4 upwardly and as tile? rods 421' move upwardly the' frame 5|k will` pivot` about thefshaf-ts Sil-auditif!!

Thus, refdrlngto, liguresA 18 and 19, the saw is shown intwo" different positions, as for trmmingbrush heads to` different. lengths. Thus, in Figure 19 the saw |3| is showninposition` for trimming brusbbeads Qi a. relativelysbcrt length, while in Figure`1`8`, the saw |31" is shown arranged for trimm-ing brush heads: ha ng a long!` or lngtl-i. `To move the-saw f; tion` ffFigure 18- tothe position'of Fig` theoperatorwreleases-iithe-Hkeeperf HI fr sector-' -platel |13 and theny raises `the arm This raising or pivotal movement of the arm |12 causes a counterclockwise pivotal movement of the link |14 and this results in the sleeve |80 being moved longitudinally along the shaft |58. As the sleeve |80 moves, it moves the hub |61 so that the platform |30a slides beneath the table |24 and thus the saw |3| moves toward the table |24. The keeper and sector plate |73 coact to maintain the saw immobile in its various adjusted positions.
